So it is not worse off. ... and that compromise is that it's not going to be possible to enable activity mode on 88e151x with how the code stands and with the independent nature of "rx" and "tx" activity control currently in the netdev trigger... making this whole approach somewhat useless for Marvell PHYs. We really need to see a working implementation for this code for more than just one PHY to prove that it is actually possible for it to support other PHYs. If not, it isn't actually solving the problem, and we're going to continue getting custom implementations to configure the LED settings. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!
